UV-crosslinkable warm-melt pressure-sensitive adhesives based on acrylics

UV-crosslinkable warm-melt pressure-sensitive adhesives based on acrylics The target of this article is to show the preparation of new generation of UV-crosslinkable warm-melt acrylic pressure-sensitive adhesives (PSAs) and the experimental test of their adhesive properties in comparison with typical conventional hot-melts adhesives. New generation of UV-crosslinkable acrylic warm-melts PSAs containing unsaturated photoinitiator, incorporated during polymerization process into polymer chain, and photoreactive diluents added to PSA systems after polymerization allows producing of wide range of self-adhesive materials, such as labels, mounting tapes, masking and splicing tapes, and sign and marking films.
